Death Letter Blues

I saw a documentation about where black music is coming from. polyrhthms were brought from the first slaves displaced from Africa to North America. Songs based on these rhythms were sung to make their work livable. These first working songs and chants had a massive influence in every kind of blues genre and gospel. Many jazz musicians a hundred years ago adapted some of this songs and named them as a heavy influence to their music. Rock and Roll brought the black music to the white people and established this music with all it's facets in contemporary music. It spreads from the early Son House with his powerful slide guitar to African drums based Detroit House like Drexciya.
